' 2 claims. (o1. 215-73) My invention consists of improvements indispensing devices it being in the nature of an adjustable telescopicdrinking tube, detachable, which is confined within a bottle or ilaskwhen the bottle cap or closure is attached, and so constructed that whenthefclosure is removed the upper section of said tube will be forced, bymeans of an inclosed spring, to protrude beyond the mouth of said bottleor flask. 'Ihe lower section of said tube remains stationary and alwayssuiliciently immersed in the liquid contents. toenable the user to'drink said contents as with an ordinary straw or drinking tube, exceptthat it will not be necessary to handle the tube hereinafter described.Y v

One object of the invention is to provide an economical and practicaldispensing device in the form of a telescopic drinking tube made ofglass, cellulose, or other similar inexpensive material `which isimpervious and immune from corrosion, disintegration, etc., when broughtin contact with ordinary liquids.

Another -object of theinvention is to provide a supporting structure,made of cork and hard 25 rubber, through which the tube is placed andwhich when inserted in the neck of the bottle supports both the upperand lower sections of said tube.

Another object of the invention is to provide a sliding or adjustablesection at the upper end of said tube which will be confined within thebottle or flask when the closure is attached and which will protrudebeyond the mouth of the bottle when the closure is removed. 3 Anotherobject of the invention is to provide a means of equipping bottles andflasks of the ordinary screw-cap and crimped-cap types with a sanitaryremovable drinking tube which may be changed from one bottle or flask toanother as desired and used indefinitely. Y

Another object of the invention is to provide a drinking tube connedwithin the bottle or flask when sealed and telescoping beyond the mouthof said container when the closure is removed, the lower end of saidtube remaining always sufficiently near the bottom of the container thatthe entire contents may be imbibed.

The form of the invention is more accurately 50 described andillustrated in the accompanying drawing wherein: l

Figure 1 is a View of a bottle of the screw-cap type showing, amongother things, the closure attached so as to force the sliding section ofthe tube downward by compressing the spring,

until the bottle is sealed in the same manner as if the tube were notpresent.

Figure 2 is an enlargement of the upper p0r- .tion of the tube showinginmore accurate detail the sliding section, spring retainer and parts,

and the frustum effect moulded near'the lower end of said section.

Figure 3 is a view o f the tube asl a whole, without the bottle andscrew-cap closure, showing the position of the sliding section of thetube when the lclosure is removed thereby allowing the spring to expandand force the upper end of said would bemade wherein the numeralsindicatei I the metal portion of bottle cap; 2 the cork insulationunderneath the bottle cap; 3 the cork insulation surrounding thespring-retainer housing; 4 the spring-retainer housing of hard rubber; 5a flange near upper end of sliding section of tube to restrain thespring; 6 the enclosed spring; 'I the spring retainer; 8 the slidingsection of tube; 9 a frustum moulded on sliding section, near lower endthereof; I0 a flange on lower end of spring retainer; II a ange on upperend of lower or stationary section of tube; I 2 a cork gasket; I3 a angeon lower end of sliding section; I4 the lower or stationary section oftube; I5 the bottle; I6 screws; I'I corrugated efect at lower end oftube; I8 the disklike closure at upper end of spring retainer.

It will be observed that the tube is held in place by a supportingstructure composed of an outer layer of cork insulation 3 and an innerlayer of hard rubber 4. The purpose of the cork insulation is tolprotect the contents of the bottle or flask from the rubber whichotherwise` would tend to give the liquid an unpleasant taste and odor.The rubber inner layer is provided because of its greater resiliency anddurability. Through a vertical opening in the center of said supportingstructure the lower section I4 of the tube is inserted and extendsdownward to the bottom of the bottle or flask. Flange I I is constructedwith an opening in the center just large enough to admit the smallerange I3 which is passed through said opening into the larger section oftube, being restrained by the cork gasket I2 from passing back throughsaid opening when the closures I and 2 are removed from the bottle orflask and the spring 6 is released. The pressure exerted by the springwhen the closure is removed brings flange I3 in contact with the corkgasket which in turn isv brought flush against flange II thereby sealingthe joint or coupling between the two sections 8 and I4 of the tube thusforming a continuous tube from the bottom of thek bottle vor flask toand beyond the mouth of said container, permitting the contents to beimbibed as with a straw or the ordinary drinking tube.

It will be noted that the retainer 1 for the spring and sliding sectionof tube is also inserted into the vertical opening of said supportingstructure so that flange I0 at the lower end of said retainer restsflush on flange II at upper end of stationary section of tube.

It will'be understood that the stationarysection I4 of the tube and thespring retainer I are forced into the vertical opening of saidsupporting structure with sumcient pressure to prevent the contents ofthe bottle or flask from seep- `ing into the retainer and spring therebyeliminat ing the possibility of rust or corrosion. y

It will be understood that frustum 9 when the bottle or flask is sealedwill be forced into the opening at the center of flange I0 at the lowerend of the retainer with such pressure as to pre- Vvent the liquid fromseeping into said retainer and spring, again eliminating the possibilityof yrust orr corrosion.

said tube may be resting on the bottom of the bottle or flask. i

Having thus fully described Vmy invention, what I claim as new anddesire to secure by Letters :Patent is:

l. A dispensing device'substantially as herein described, comprising a.bottle or flask, a closure therefor, and a telescopic drinking `tubefitted within said bottle or flask by means of a. cylindrical structurevwhich serves as a coupler and `supports both the upper and lowersections of said tube, the lower section of which is stationary andextends downward from Within said cylindrical structure to the bottom ofthe bottle or flask, whereas the upper section is adjustable, beingconfined within the bottle or flask and said cylindrical structurewhenthe closure is attached, and by means of an inclosed spring beingforced to yprotrude beyond the mouth of said bottle or flask when theclosure is removed.

2. A dispensing device substantially as herein described, comprising abottle or flask, a closure therefor, and'a sectional telescopic'drinkingtube fitted within said bottle or flask by means of a supportingstructurel which serves as a coupler and supports the sections of saidtube,.one

section being stationary and extending down ward 'tothe bottom of thebottle or flask, whereas one section is adjustable, being confinedwithin the container and supporting structure when the closure isattached-and, by means of an inclosed spring, forced to protrude beyondthe mouth 'of ysaid container when the closure is removed.
